Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment sedimentation tank. Background Technology

[0002] Wastewater treatment refers to the removal of pollutants from wastewater using physical, chemical, and biological methods to meet discharge standards that are harmless to the environment and human health. Sedimentation tanks are an important component of wastewater treatment systems, used to separate solid particles and sediments from wastewater using gravity. In sedimentation tanks, the wastewater flow rate slows down, and solid particles settle to the bottom due to gravity, thereby removing suspended solids and some pollutants.

[0003] Existing wastewater treatment sedimentation tanks typically allow water to be directly fed into the treatment tank, with the supernatant discharged via overflow. However, when wastewater is directly fed into the treatment tank, large particles of sludge enter the tank along with the wastewater. The large amount of large particles entering the treatment tank can easily increase the overall treatment pressure, resulting in more sediment in the tank and thus increasing the frequency of cleaning. This makes it unsuitable for long-term wastewater treatment. Therefore, we propose a wastewater treatment sedimentation tank. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment sedimentation tank to solve the problem mentioned in the background art of increasing the cleaning frequency of the entire treatment tank due to the large amount of large particulate matter entering the treatment tank.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment sedimentation tank, comprising a treatment tank, a primary filter element disposed at the top of the treatment tank, a support block fixedly connected to the side wall of the primary filter element, a support frame fixedly connected to the top of the treatment tank, a limit ring disposed inside the support frame, limit rods fixedly connected to the support frame at both ends of the limit ring, an opening and closing component disposed on the side wall of the limit ring, a locking ring disposed on the side wall of the opening and closing component, a water receiving plate rotatably connected inside the primary filter element, a strong spring disposed at the top of the water receiving plate, and a fixed block disposed at the top of the strong spring.

[0006] Preferably, the treatment pool has an overflow trough on its side wall, an intercepting net is installed inside the overflow trough, a net box is installed on the top of the overflow trough, and a snap-fit ​​strip is fixed to the outer wall of the net box.

[0007] Preferably, a support plate is provided at the top of the overflow trough, and a sliding hole is provided on the side wall of the support plate. A multi-hole air blowing pipe is fixedly connected to the left side wall of the support plate.

[0008] Preferably, the sidewall of the interception net is provided with a push plate, and sliding blocks are fixedly connected to both ends of the push plate.

[0009] Preferably, a telescopic rod is provided on the top of the sliding block, the telescopic rod is fixed to the side wall of the support plate, and the telescopic rod is electrically connected to a microcontroller.

[0010] Preferably, the top of the water receiving plate is provided with multiple protrusions, and the water receiving plate is fitted to the top of the opening and closing component.

[0011] Preferably, the top of the treatment pool is provided with a notch, and the support block fits into the inside of the notch.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a pre-filter with a water-receiving plate installed at the top of a wastewater treatment sedimentation tank. When the opening and closing mechanism is opened, the external pipe is locked with a locking ring. Wastewater from the external pipe first flows onto the water-receiving plate, where it is impacted by the wastewater, and then falls into the pre-filter, where larger impurities are intercepted. Finally, the wastewater flows into the sedimentation tank for settling. The pre-filter can be slid to the right with a recessed opening and can be removed from the treatment tank for discharge. This allows for convenient filtration of larger impurities in wastewater, reducing the amount of larger impurities entering the sedimentation tank, reducing the treatment pressure on the sedimentation tank, and decreasing the overall cleaning frequency of the sedimentation tank.

[0014] 2. In this invention, after the sewage settles inside the treatment tank, the upper layer of clear water passes through the interception net and is discharged from the overflow trough. At this time, the dirt on the surface of the clear water is intercepted by the interception net. The telescopic rod is in the extended state, so that the push plate is located at the bottom of the inner side of the interception net. When the time set by the microcontroller is reached, the telescopic rod retracts, causing the push plate to move upward and scrape the dirt inside the interception net to the top of the push plate. When the push plate moves to the top of the interception net, the external air pump connected to the multi-hole air blowing pipe runs, causing the multi-hole air blowing pipe to blow air towards the top of the push plate, so that the dirt on the top of the push plate is blown into the inside of the net box. Finally, the air pump is turned off and the push plate returns to the bottom of the interception net, thereby realizing convenient cleaning of the inside of the interception net, avoiding the blockage caused by a large amount of dirt inside the interception net, which is conducive to the long-term stable operation of the treatment tank and saves the trouble of manually cleaning the interception net.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figures 1-5The diagram shows a wastewater treatment sedimentation tank, including a treatment tank 100. A primary filter element 110 is snapped onto the top of the treatment tank 100. The primary filter element 110 is made of a stainless steel ring at the top and a large-mesh stainless steel filter screen at the bottom. A support block 111 is bolted to the side wall of the primary filter element 110. A support frame 120 is bolted to the top of the treatment tank 100. A limit ring 121 is provided inside the support frame 120. Limiting rods 122, which are fixed inside the support frame 120, pass through both ends of the limit ring 121. An opening and closing element 130 is provided on the side wall of the limit ring 121, and a locking ring 13 is provided on the side wall of the opening and closing element 130. 1. The locking ring 131 is equipped with common locking bolts on both sides. When the locking ring 131 is engaged with the opening and closing part 130 at the outlet of the external pipe, the locking bolts can be used to lock the external pipe. The water receiving plate 140 is rotatably connected inside the primary filter element 110. The water receiving plate 140 is a common hollow aluminum alloy plate. A strong spring 143 is provided on the top of the water receiving plate 140. The strong spring 143 is made of common stainless steel spring with high elasticity, so that the water receiving plate 140 can rotate downward when impacted by water flow. A fixing block 142 is fixedly connected to the top of the strong spring 143 and is set on the inner wall of the primary filter element 110.

[0026] Specifically, the treatment tank 100 has an overflow trough 150 on its side wall, an interception net 151 inside the overflow trough 150, and a mesh box 181 on the top of the overflow trough 150. The mesh box 181 is made of common dense stainless steel filter mesh, which can allow air to pass through while intercepting dirt in the airflow. The outer wall of the mesh box 181 is fixed with a snap-fit ​​strip 182 by bolts. When it is necessary to clean the mesh box 181, the mesh box 181 can be pulled upwards to allow the snap-fit ​​strip 182 to slide with the overflow trough 150, thereby disassembling and cleaning the mesh box 181.

[0027] Furthermore, a support plate 160 is provided on the top of the overflow trough 150, and a sliding hole 161 is provided on the side wall of the support plate 160. A multi-hole air blowing pipe 180 is fixed to the left side wall of the support plate 160, and a commercially available external air pump is provided at the input end of the multi-hole air blowing pipe 180, which is electrically connected to the microcontroller 171.

[0028] Furthermore, the side wall of the interception net 151 is provided with a push plate 162, and sliding blocks 163 are fixedly connected to both ends of the push plate 162.

[0029] Furthermore, a telescopic rod 170 is provided on the top of the sliding block 163. The telescopic rod 170 is a commonly available waterproof electric push rod. The telescopic rod 170 is fixed to the side wall of the support plate 160. The telescopic rod 170 is electrically connected to a microcontroller 171. The microcontroller 171 is a commonly available programmable controller. By pre-setting the running time of the telescopic rod 170 and the external air pump, the telescopic rod 170 and the external air pump work together to clean the interception net 151.

[0030] It is worth noting that the top of the water receiving plate 140 is provided with multiple protrusions 141, and the water receiving plate 140 is fitted to the top of the opening and closing part 130.

[0031] It is worth noting that a notch 112 is provided on the top of the treatment pool 100, and the support block 111 fits into the interior of the notch 112.

[0032] In addition, all the electrical components and equipment mentioned above use external power sources. The circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0033] Working principle: By setting a primary filter element 110 with a water receiving plate 140 at the top of the wastewater treatment sedimentation tank, the external pipe can be locked with the locking ring 131 when the opening and closing part 130 is opened. At this time, the sewage from the external pipe is first discharged to the water receiving plate 140 and receives the impact of the sewage. Then it falls into the primary filter element 110, which can intercept larger dirt. Finally, the sewage falls into the sedimentation tank for sedimentation. The primary filter element 110 can slide to the right with the notch 112 and can be removed from the treatment tank 100 for sewage discharge. This allows for convenient filtration of larger contaminants in wastewater, reducing the amount of larger contaminants entering the sedimentation tank, decreasing the treatment pressure on the sedimentation tank, and reducing the overall cleaning frequency of the sedimentation tank. After the wastewater settles inside the treatment tank 100, the upper layer of clear water passes through the interception net 151 and is discharged from the overflow trough 150. At this time, the contaminants on the surface of the clear water are intercepted by the interception net 151. The telescopic rod 170 is in the extended state, causing the push plate 162 to be located at the bottom inside the interception net 151. When the time set by the microcontroller 171 is reached, the telescopic rod 170 retracts, causing the push plate 162 to move upward and the interception net 151 to be removed. The dirt on the inside is scraped to the top of the push plate 162. When the push plate 162 moves to the top of the interception net 151, the external air pump connected to the porous air pipe 180 runs, causing the porous air pipe 180 to blow air towards the top of the push plate 162, so that the dirt on the top of the push plate 162 is blown into the inside of the net box 181. Finally, the air pump is turned off and the push plate 162 returns to the bottom of the interception net 151, thus realizing convenient cleaning of the inside of the interception net 151, avoiding the blockage caused by a large amount of dirt inside the interception net 151, which is conducive to the long-term stable operation of the treatment pool 100 and saves the trouble of manually cleaning the interception net 151.
